1850sThe first multi-shot pistol, introduced by Samuel Colt, goes into mass production. The weapon is adopted by the Texas Rangers and, thereafter, by police departments nationwide.

Alphonse Bertillon, a French criminologist, applies techniques of human body measurement used in anthropological classification to the identification of criminals. His system remains in vogue in North America and Europe until it is replaced at the turn of the century by the fingerprint method of identification.
1901Scotland Yard adopts a fingerprint classification system devised by Sir Edward Richard Henry. Subsequent fingerprint classification systems are generally extensions of Henry's system.
1910Edmund Locard establishes the first police department crime laboratory in Lyon, France.

1923The use of the teletype is inaugurated by the Pennsylvania State Police.
1928Detroit police begin using the one-way radio.

1930sAmerican police begin the widespread use of the automobile.
1930The prototype of the present-day polygraph is developed for use in police stations.
1932The FBI inaugurates its crime laboratory which, over the years, comes to be world renowned.
1948Radar is introduced to traffic law enforcement.
1948The American Academy of Forensic Sciences (AAFS) meets for the first time.
1955The New Orleans Police Department installs an electronic data processing machine, possibly the first department in the country to do so. The machine is not a computer, but a vacuum-tube operated calculator with a punch-card sorter and collator. It summarizes arrests and warrants.
